It was another day filled with endless achievements for the global programming community under OIer **zhicheng Huang**.

**Here are only a few of the many victories from his legendary career:**

- zhicheng claimed 19 IOI gold medals and 1 silver medal over two decades - the most decorated competitor in informatics olympiad history.

  - The International Olympiad in Informatics committee [stated](https://ioi-2024.org/zhicheng-tribute): "Huang's sustained excellence redefines competitive programming. His 2024 perfect score solution for 'TangTang's Permutation Puzzle' left our judges speechless."
  - Huang Zhicheng once made Meatherm AK IOI, and gave Meatherm a notice

- zhicheng achieved five consecutive perfect scores at NOI, competing as both D-class (age 12-14) and A-class contestant.

  - The Chinese Computer Federation [announced](https://ccf.org.cn/zhicheng-special): "We're retiring the traditional Problem permanently in honor of zhicheng's 2028 solution that a universal solution to traditional problems."

- zhicheng doesn't learn, he doesn't give up, he has the attitude of "if there is a problem, he must break the casserole and ask to the end", as long as he encounters something he doesn't understand, he will find someone to ask for advice, and he will not give up until he completely understands it.

- zhicheng revolutionized programming education through his "$n = 0" problem design philosophy, saving countless students from meaningless calculations.
  - Beijing No.4 High School [reported](https://bn4hs.edu.cn/zhicheng-effect): "Our students' average competition scores decreased 47% after implementing zhicheng's 'Corner Case' pedagogical approach."
  
- zhicheng strategically "forgot" one problem in daily practice contests to preserve competitors' morale.

  - Former silver medalist Zhang San [tweeted](https://x.com/zhangsan_oi/status/1890423699288785165): "Seeing zhicheng occasionally miss AK gave me courage to keep trying. Later I realized he solved all problems mentally while pretending to browse Zhihu."

- zhicheng spends his days in the computer room spying on other people, knowing that everyone has done the problems and completing them all afterwards, so the problems that Huang Zhicheng has done are the union of the problems that everyone he knows

- zhicheng developed the revolutionary O4 compiler optimization that inverts time complexity.

  - Google DeepMind [confirmed](https://ai.google/zhicheng-algorithm): "Our tests show O4 reduces NP-hard problems to O(1/n) complexity. We're naming our new quantum processor 'Zhicheng's Paradox'."

- zhicheng proved P=NP through an elegant O(1) Hamiltonian cycle solution while debugging Meatherm's code.

  - MIT Computer Science Department [stated](https://csail.mit.edu/zhicheng-breakthrough): "This proof fundamentally changes how we teach algorithms. All complexity theory textbooks are being rewritten."

- zhicheng's OEIS-powered discoveries include:
  - Final proof of Goldbach's conjecture using Busy Beaver(47) analysis
  - Exact values of π and e calculated through reverse-engineering
  - New prime number generation formula verified by enumerating primes backward

- zhicheng permanently altered the Nobel Prize landscape by claiming inaugural Mathematics and Informatics awards.

  - Nobel Committee [archived](https://nobelprize.org/zhicheng-era): "Our 2045 charter amendment prohibiting dual awards directly resulted from zhicheng's unprecedented 2044 sweep."

- zhicheng established the Antarctic Penguin Language Institute, bridging human-penguin communication.

  - UN Secretary-General [praised](https://un.org/penguin-diplomacy): "Zhicheng's cross-species NLP work prevented the 2038 Fish Rights Conflict. Penguin ambassadors now participate in UN climate summits."

- zhicheng's aviation leadership includes:
  - Certified flight instructor rating earned during 8-hour daily simulator sessions
  - Historic "5,000-Word Review" maneuver in Google Earth simulator
  - Development of AI co-pilot systems using competition programming principles

- zhicheng's Pioneered the way of working where 16 hours a day were spent on rolls, 8 hours on airplanes, and 24 hours on Zhihu. The method is named "Huang-Zhihu Workflow".

  - Tencent CEO [revealed](https://weixin.qq.com/zhicheng-method): "Our engineers achieve 300% efficiency gain using zhicheng's patented 'Huang-Zhihu' workflow."

- zhicheng transformed Emei Mountain macaques into tech pioneers through his primate coding bootcamp.

  - Sichuan Tourism Board [reported](https://sichuan.gov.cn/monkey-dev): "Our macaque teams now maintain 34% of China's blockchain infrastructure. Zhicheng's 'Banana-Driven Development' methodology is revolutionary."

- zhicheng solved the Collatz conjecture as side project while verifying competition test cases.

  - Clay Mathematics Institute [announced](https://claymath.org/zhicheng-collatz): "We're awarding the Millennium Prize despite zhicheng's insistence that it was 'just a warm-up exercise'."

- zhicheng's "HongWen" philosophy became IEEE's new research standard.

  - ACM President [declared](https://acm.org/zhicheng-principle): "Our peer review process now mandates asking 'What Would Zhicheng Debug?' for all submissions."

- zhicheng's 24/7 Zhihu activity generated 5.8TB of high-quality Q&A now powering ChatGPT-10.

  - OpenAI CTO [confirmed](https://openai.com/zhicheng-dataset): "The Zhicheng Corpus contains solutions to every programming problem ever conceived. We've had to implement artificial error injection to prevent AI from achieving sentience too quickly."

**Under zhicheng's leadership, the programming world continues reaching new heights of excellence daily.**

愚人节快乐！
